THE RIFT between Europe and America became a chasm last night as senior Euro boss Donald Tusk attacked Donald Trump as being against everything Europe and the EU stands for.

Ahead of this week's NATO summit, the US President weighed in on the European Union, NATO and the WTO claiming that the multilateral organisations are 'bad for America'.

But European Council leader Tusk countered by telling EU leaders Trump posed a threat to long-established post war Western alliances - and warned the president’s position should be taken deadly seriously.

Aides confirmed that his comments were made in a series of private meetings used to warn against the threat that Mr Trump posed to the West's multilateral organisation.

According to The Times, Mr Tusk said: “He has a method and is serious in his mission against an international rules-based order.

One diplomatic aide said that at the G7 summit the president had told the prime minister of a European country that he “can’t stand” German chancellor Angela Merkel, “because that woman embodies everything that I hate”

According to another account, when French President Emmanuel Macron visited the White House in April Mr Trump urged him to withdraw from the EU and instead secure a more favourable bilateral trade agreement with Washington.

Mr Trump suggested to the Swedish prime minister in March that America should leave NATO, in comments his aides later said were a joke.

The paper Washington Post reported that Pentagon officials have been ordered to calculate the costs of a large-scale withdrawal of US troops from Germany.

Last night, Mr Trump reiterated his belief that NATO members should spend more on defence. Speaking to reporters on board Air Force One as he flew to his New Jersey golf resort, the president said: “Germany has to spend more money. Spain, France, it’s unfair what they’ve done to the United States.”
